L99VR02J Automotive LDOs

STMicroelectronics' L99VR02J in a PowerSSO-12 package is a low dropout linear voltage regulator designed for automotive applications. The LDO delivers up to 500 mA of load current. It consumes as low as 1 μA of quiescent current when the regulator is disabled. The input is 40 V tolerant to withstand load dump, while the operating input voltage range is between 2.15 V and 28 V.

The L99VR02J can be configured, through SELx pins, to generate a fixed selectable output voltage (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.8 V, 3.3 V, or 5 V). High output voltage accuracy (±2%) is kept over wide temperature range, line, and load variation.

The L99VR02J features enable, reset, autonomous watchdog, advanced thermal warning, fast output discharge, and I_Short control. The regulator output current is internally limited. The device is protected against short-circuit and overload and features overtemperature protection. The short current value is configurable by external resistance. The L99VR02J can operate in post regulation attached to a preregulated voltage or directly connected to the battery.
